^Rog will continue to wear collars for the rest of his carrear.
I think so, yes. It sort-of fits the image Nike wants to sell for him. It's the same curse of Rafa having to wear sleeveless and pirate pants all the time.
In all, it represents the way marketers (boy I hate those fellows!) think of the general public: as *shallow* more than anything else... unfortunately, they often are right about that.
Back on topic: I kinda like those shirts with the white collar. And the BLACK outfit, of course.
EDIT: thanks for posting, X!
